1. Super Absorbent Polymer Powder,super absorbent polymer 

The filling of diapers, Super Absorbent Polymer power, is a new type of functional polymer material. It has a high water absorption function of absorbing hundreds to thousands of times heavier than itself, and has excellent water retention performance. Once it absorbs water and swells into a hydrogel, it is difficult to separate the water even if it is pressurized.

2. Characteristics of Super Absorbent Polymer Powder

Super Absorbent Polymer power are low-crosslinking or partially crystalline high-molecular polymers with many hydrophilic groups. Super Absorbent Polymer power has high water absorption, can absorb water dozens of times its own weight, the water absorption speed can generate gel in a few seconds, and the volume of the gel can be expanded dozens of times immediately; at the same time, it is insoluble in water and has high water retention, Water is not easily squeezed out of the gel after absorbing water under external pressure.

3. Raw materials of Super Absorbent Polymer Powder

Super Absorbent Polymer power are macromolecules containing hydrophilic groups and cross-linked structures. They were first prepared by Fanta et al. by grafting starch with polyacrylonitrile and then saponifying it. According to the raw materials, there are starch systems (grafts, carboxymethylation, etc.), cellulose systems (carboxymethylation, grafts, etc.), synthetic polymer systems (polyacrylic acid, polyvinyl alcohol, polyoxyethylene) Vinyl, etc.) several categories.
